The prevalences according to ethnic group do not closely follow the ethnicity proportions in the general population, because of differences in the prevalence of PWID and the prevalence of HCV infection in PWID between ethnic groups.
For summary data from Cohort 5, we only estimated ethnicity proportions.
There were no significant differences in terms of gender, ethnicity, and proportion with secondary infection.
For ethnicity, the proportion of respondents describing themselves as white British was similar to the general population.
29 The reason for this remains unclear, but may be attributable to an older population of Irish ethnicity whose proportion is three times higher than the UK population.
Subgroup analyses were conducted according to the ethnicity, the proportion of Fuhrman grade III-IV patients, and duration of follow-up.
Because our study relied on clinician and microbiologist reporting of ethnicity, the proportion of patients reported as white may have been overestimated as a result of assumptions made without confirmatory information.
*Race/ethnicity was collected as two variables in the survey and one variable in the census (including Hispanic/Latino ethnicity), thus proportions do not match text Twenty-three (12%) respondents reported ever injecting drugs, 39 (20%) reported having had a blood transfusion, and 10 (5%) were men who reported ever having sex with another man.
During the study period, the widest changes in ethnicity-specific proportion of patients excluded were for liver, lung, and ovarian cancers and for NHL, whereas survival in South Asians either became worse than in non-South Asians (NHL) or dropped dramatically (lung).
Overall proportions from minority ethnic groups are similar to London as a whole but the composition is different, with higher proportions with self-assigned Black ethnicity and lower proportions Asian.
25 We had no data with which to assess variation by ethnicity in the proportion of patients assessed who were diagnosed with CFS/ME.
